Filed: 1988-11-15
Abstract: A die head (10) is disclosed for use on an extruder die comprising a plate-like structure (11) having an elongated slot (12) through which extrudate (30) is extruded. The slot has a central area which is narrower than the height at each end of the elongated slot. The elongated slot (12) also is arcuate in shape, and the central area to each portion is a mirror image of one another. The die head (10) produces an extrudate (30) which is uniform in thickness throughout a cross-section taken normal to the direction of extrusion, but the extrudate is bowed or arcuate in shape. The combination of a metallic shell (40) and a flexible arcuate magnetic material (30) is also disclosed in which the extruded flexible magnetic strip material is curled within the cylindrical shell (40) such that both the peripheral exterior surface (38) and the peripheral interior surface (39) of the flexible magnetic material is flat in axial cross-­section.

Abstract: Tischtschenko condensation of aldehydes is used to remove aldehydes from dry ketone-containing streams. The Tischtschenko condensation is used to condense the aldehydes into esters whose boiling points are significantly different than the ketones, greatly simplifying the separation of the esters from the ketones. An organic extraction step is used to obtain a substantially dry ketone containing stream. One particularly preferred class of extraction solvents is selected from the group consisting of butane, pentane, hexane, heptane, octane, nonane, decane and mixtures thereof. In particularly preferred embodiments, the Tischtschenko reaction is used in the context of aqueous-phase catalyzed olefin oxidation to ketones. The aldehyde to ester condensation permits easy and efficient removal of the aldehyde analogs of the desired ketones.

Abstract: Apparatus and a method of correcting for repeatable positioning errors in an X-Y table is provided. An accurate mask is provided having a plurality of repetitive recognizable patterns thereon which is placed in the field of view of a pattern recognition system of a semiconductor processing machine to be calibrated. The semiconductor processing machine is programmed to perform a series of steps which steps the X-Y table to positions which are supposedly accurate relative to a fixed point. At each of the stepped points, the plurality of repetitive recognizable patterns on the mask are electronically scanned by the pattern recognition system and the deviation of the position of the pattern relative to the desired position is calculated to provide X and Y deviations from the theoretical position of the X-Y table. These deviations of points along a linear X and a linear Y axis are employed to calculate the actual deviations of other pattern points for all of the possible positions of movement along other X and Y axes.

Abstract: For testing coils for shorts between turns and/or layers, it is proposed to connect the coil into a series resonant circuit and to carry out a quality-factor measurement by measuring the voltage peak at resonance, in which arrangement the resonant frequency is placed, by selecting a suitable capacitance in the series resonant circuit, into a range in which the coil quality factor reaches its maximum. Thus, the coil to be tested is a component of a series resonant circuit, the measuring system for detecting the quality factor of the coil being coupled with low capacitance into the resonant circuit. The method described and the associated device can be used, in particular, when the interturn resistance of the test specimen must be measured in any case since this value is also obtained during the quality factor measurement. This makes it possible to optimise the handling and measuring times needed.
